Not too big of a fan of the runecrafting one so here's mine:
Runecrafting:
Allows you to craft runes from essence directly from your pouches.
Some of the capes could also save an inventory space by providing their tools, this could be done either instead or in addition to the current ideas:
Construction:
Acts as a hammer and saw when building things in your PoH.
Smithing:
Acts as a hammer when smithing bars on anvils.
Crafting:
Acts as unlimited thread.
Fishing:
Acts as every fishing tool. (not including bait)
Slayer:
Acts as any finishing weapon so long as the player has unlocked faster finishes for that creature.
Hunter:
Acts as every type of cammo.
Farming:
Acts as a seed dibber.
As for the combat capes those are easy:
Attack Strength Defence:
Allows you to afk for more than 20 minutes if wearing full guthans.
Magic:
Allows you to afk for more than 20 minutes if wearing full iron armor and holding a smoke battle staff.
Ranged:
A check option on the cape that tells you how many of each chin you've thrown and their total worth by current ge prices.
Also I liked your idea for sailing but here's a better one:
Sailing:
Allows you down vote two times per poll. I realize this might be OP so maybe limit this feature only to people who don't read the dev blog, or are mad about something unrelated that jagex did.
((The combat and sailing capes are jokes, apparently some people don't recognize sarcasm.))
